C#实现GZip压缩和解压缩入门实例

byte[] cbytes = null;
//压缩
            using (MemoryStream cms = new MemoryStream())
            {
                using (System.IO.Compression.GZipStream gzip = new System.IO.Compression.GZipStream(cms,System.IO.Compression.CompressionMode.Compress))
                {
                    //将数据写入基础流，同时会被压缩
                    byte[] bytes = Encoding.UTF8.GetBytes("解压缩测试");
                    gzip.Write(bytes, 0, bytes.Length);
                }
                cbytes = cms.ToArray();
            }
//解压
            using (MemoryStream dms = new MemoryStream())
            {
                using (MemoryStream cms = new MemoryStream(cbytes))
                {
                    using (System.IO.Compression.GZipStream gzip = new System.IO.Compression.GZipStream(cms, System.IO.Compression.CompressionMode.Decompress))
                    {
                        byte[] bytes = new byte[1024];
                        int len = 0;
                        //读取压缩流，同时会被解压
                        while ((len = gzip.Read(bytes, 0, bytes.Length)) > 0)
                        {
                            dms.Write(bytes, 0, len);
                        }
                    }
                }
                Console.WriteLine(Encoding.UTF8.GetString(dms.ToArray()));
            }
